The High Purity Fused Silica Quartz Boat is a precision-formed high-temperature carrier engineered for tube furnace sintering, semiconductor processing, and laboratory thermal applications. Manufactured through integral hot-forming for uniform wall thickness and fine-polished surfaces, it delivers outstanding thermal stability up to 1100°C, superior chemical resistance to hydrofluoric acid and concentrated corrosive reagents, and zero impurity precipitation — ensuring contamination-free processing for the most demanding industrial and research environments.
| Industry | Application |
|---|---|
| Tube Furnace Sintering | Carrier for high-temperature calcination of powders, wafers, and ceramic substrates in controlled-atmosphere tube furnaces |
| Semiconductor Processing | Wafer annealing and pre-coating high-temperature pretreatment tray ensuring ultra-clean, contamination-free conditions |
| Laboratory Testing | Ashing experiment and corrosive immersion sample container for analytical chemistry and materials characterization |
| New Material R&D | Powder synthesis and precursor heat treatment vessel for advanced material development |
vs. Borosilicate Glass Boat: Borosilicate glass cannot withstand hydrofluoric acid and softens at high temperatures; this quartz boat resists strong corrosion and maintains mechanical integrity through repeated 1100°C thermal cycling without deformation or cracking
vs. Alumina/Ceramic Boat: Superior thermal shock resistance enables rapid heating-cooling; transparent wall allows visual process monitoring; zero metal impurity eliminates wafer and sample contamination risk
